Frozen human embryos are collapsing fertility clinics capacity of storage. Bioethical approach

Frozen embryos abandoned. Short review Earlier this year, CBS News published an interesting review with the evocative title Tens of thousands of embryos are stuck in limbo in fertility clinics, an issue we have addressed several times in our Observatory because it is a great...

Three-dimensional models of human embryos generated using human stem cells

The development of anterior-posterior symmetry of the human embryo occurs during pregnancy. Many of the signals that regulate this process have been described in experiments using mice. However, there is no direct molecular evidence of how anterior-posterior symmetry is achieved...

Another molecular revolution. The atlas of human embryonic development

We publish the full text of the article published in the Civica magazine last January (Spanish version HERE) that we consider of great bioethical interest. By now, at this advanced stage of biology in which we find ourselves, no one should doubt that each human individual, each...

Scientific institutions are trying to devise global safeguards to stop rogue gene-editing of human embryos

Some U.S. researchers knew of a Chinese scientist’s intentions to implant edited embryos but were unable to stop him. A recent article makes an update of the measures that the scientific community is implementing to avoid implantation of edited embryos. It says  Now, nearly two...

The status of person of the human embryo

“The ultimate postmodern injustice is the refusal to recognise certain human individuals as persons” * Introduction The continuing advances of science in the area of embryology leave little doubt about the human nature of the embryo of our species. Biologically, there...

Nature changes its policy allowing experimentation with human embryos. Why?

Nature Group does not explain the reasons for this change. In any case, the question remains if its decision is based on new scientific evidence. Research using human embryos and embryonic stem cells has prompted a fierce ethical debate. As editors of these types of studies, the...

Human embryos research and the Politics of Bioethics

Ethical objective questions posed by human embryo experimentation are exacerbated by the deregulate gene editing techniques research including biohackers A book has been published by Columbia University, entitled “Experiments in Democracy. Human Embryo Research and the Politics...

Moral assessment of frozen human embryos adoption in the Magisterium of Catholic Church

Our Observatory published a paper in the journal Acta Bioética that for its relevance we want to make known our readers. The criterion of the Catholic Church in addition to giving a moral instruction to its faithful is an undoubted reference, in so difficult matter, for all the...

Frozen embryos donation figures. Human embryos transferred increased over the years

It is difficult to find objective data on the practice of embryo donation. Now, a study published in the American Journal of Obstetrics and Gynecology has provided data on this topic for the period 2000 to 2013 in the United States. As we know, with the use of in vitro...

Scientists cloned human embryos and modify their genome. Medical and ethical approach

The technique has 2 ethical difficulties human embryo cloning and germline modifications Over the last few months, several articles have been published reporting genome editing experiments on human embryos (See HERE  ). Now, a team of Chinese researchers has published a new study...
